3.3 Mothers Know Best

Dorothy and the Tin Man passed by a "DEF TUV TUV OPER OPER" poster
as they walked down the Infinite Corridor. "Tin Man, who do you talk to when
that heart of yours needs some advice?"

"Why, my mother, of course! Trouble is, she hasn't gotten her heart
yet; she's been on the transplant list for years. But nonetheless, she
somehow manages to have all the answers." The Tin Man paused for a
moment, then added, "That is, unless I call her before 10 a.m. or
after 10 p.m. (her time). In that case she won't even pick up the
phone. Does your mother do that?"
